If Your 2010 Lexus IS250 has the check engine light come on at the same time as the traction control light that usually means that there was a fault detected somewhere with the transmission or the driveline. However the traction control light will sometimes turn on every time You get a check engine light. I recommend using an OBD II scan tool to read the ECU and determine what code was thrown. It can be something as simple as a loose gas cap on the car, all the way to something as complexAs total engine failure. There's no way to know unless You see what the ECU says has happened in the car.

The check engine light on the 2010 lexus is250 is a catch all that is designed to alert you to an issue with the vehicle. It gets turned on when the computer in the vehicle detects an error on the vehicle and stores a trouble code. You can read that code with an obd scanner and this will tell you what the issues is. Common issues can include a loose gas cap, the engine misfiring, d***y spark plugs, vacuum leaks, low oil pressure, and nearly anything else. The light can also come on to remind you to get the vehicle serviced if you are nearing a mile stone. The check engine light is not often a major issue, but it should not be ignored either.
